Leveraging Namibia's abundant year-round sunlight, the system operates fully on solar power, running off-grid with diesel generators used only in emergencies, ensuring reliable and continuous energy supply while promoting sustainable energy applications.
The project features a 45 MW / 90 MWh BESS facility, representing the country's largest battery, and is part of the broader Transmission Expansion and Energy Storage (TEES) program. Funding support for TEES is being provided through the World Bank, under Loan and Grant.
Entry-level options start at $3,800 using refurbished components, but warranty terms vary wildly. Most SMEs opt for 20-50kW hybrid systems. 08/kWh-that's 23% cheaper than Windhoek's grid electricity during peak hours.
As the sun dips below the Kalahari dunes each evening, this lithium-ion and flow battery hybrid system kicks into gear, storing enough daytime solar energy to power 90,000 homes through the night. This isn't your grandma's AA battery setup.
These cabinets are weatherproof and corrosion-resistant, making them suitable for applications such as solar farms, wind energy storage, and electric vehicle charging stations. This energy storage cabinet supports both on-grid and off-grid configurations, with harmonic distortion.
A 1MW photovoltaic energy storage power station costs around US$550,000. Cost varies depending on installation location and energy storage battery capacity.
But integrating energy storage into an existing operation requires planning. This guide provides a step-by-step approach to successfully incorporating BESS into industrial and commercial projects.
All-in BESS projects now cost just $125/kWh as of October 2025 2. With a $65/MWh LCOS, shifting half of daily solar generation overnight adds just $33/MWh to the cost of solar.
The Photovoltaic Energy Storage Integrated System (PVESS) market is experiencing robust growth, driven by increasing demand for renewable energy, grid stability improvements, and the decreasing cost of battery storage technologies.
